[mpich-discuss] Problem with MPI_File_write_all in Fortran90?

[Angel de Vicente]

Hi,

this is the first time tham I'm using MPI_File_write_all with Fortran,
so perhaps I'm doing something really silly, but as far as I can tell
these two programs that I attach (in C and in Fortran 90) should behave
the same way.

angelv$ mpicc -o parallel_i_oc parallel_i_o.c
angelv$ mpif90 -o parallel_i_of parallel_i_o.f90 
angelv$ mpiexec -n 4 ./parallel_i_oc
angelv$ mpiexec -n 4 ./parallel_i_of
angelv$ ls -lth datafile*
-rw-r--r-- 1 angelv dialout 9.8T 2012-07-23 23:45 datafile_f
-rw-r--r-- 1 angelv dialout 118K 2012-07-23 23:45 datafile_c
angelv$ 

I don't even have 9.8T in this hard disk, so something funny is going
on. Any ideas?

This is with MPICH2 version 1.4.1p1

Thanks,
